so what all involves swapping from the getrag to nv4500? will you have to shorten or lengthen driveshafts? does anyone know if you have move the crossmember and mounts? Is there any other details that maybe I am not thinking of that I need to know before I really consider a swap like this? I know advance adapters makes the adapter kit for the conversion allowing you to use the stock clutch and starter. does anyone know where I may could by a G360 or a NV4500?

Im located in southern KY so anywhere within 200 miles or so would be nice if possible but I am open to anywhere really....
